Holden Crewman Engine Problems

Ignition coil failures have been an often reported failure on Commodores going back a number of models; it's not necessarily something new. I couldn't say the others will fail any time soon, after all the two failed coils did 184,000 km before giving up.

I'm not sure of the date, but I understand the 7.7mm pitch chain was fitted to engines after number HO53340001. That should tell you if your engine was affected.

It's hard to suggest what might be wrong without seeing the car, so I suggest the best thing is to have an LPG specialist look at it. Give the people at Impco a call on 03 8788 1000 and ask them to check the car for you.

That's the problem when trying to locate the cause of leaks etc. They're not usually the obvious things you think of, like a poorly fitting or damaged seal etc. but you have to check those things first before you dig deeper and spend a lot of money in the process.

If it has come on and stayed on it means you should get it checked, it could be a number of things that caused it, and you need to have it checked by a mechanic to determine the exact cause. If there isn't any obvious change in the way the car drives there's probably not much to be concerned about, but it the car isn't running the way it was, and the light is still on get it checked.

WE PASSED this on to Peter Linahan of Autogas Australia for comment. He says: ``I am not aware of anyone who has successfully certified a kit for the new 3.6-litre V6 engine. In fact, GM Holden is yet to release an option for LPG on this engine, either through its dealer network or through Holden by Design. I am told that the kit for the LPG VY Commodore is close, but that is unlikely to suit the Crewman. ``I have also heard comments that the engine is delicate from a gas point of view and anyone contemplating a conversion would be advised to make sure any kit has been properly tested and checked. ``Being a 2004 vehicle it will require a kit that has been emission certified. ``As fuel prices move ever upward it may change Holden's marketing stance and it may choose to pursue an LPG option for that model. ``Alternatively, you could contact Impco and see if it would be interested in using your vehicle as a guinea pig if it felt there was a market for such a kit. ``I suggest contacting Paul Nolen on 9584 5644.''
